A Micrometer is widely used for precise measurement of small distances. I use a Micrometer to measure the thickness in materials like sheet metal or aluminum. You can also use a Micrometer to measure the diameter of a cylindrical shape or sphere.

This is a Metric "Caliper" style micrometer made by “Draper.” It’s manufactured from hardened stainless steel. Slider displacements are amplified by a rack and pinion mechanism and indicated on the dial. Four way measurement: internal, external, depth and step. Reading 0.02mm. Slider has lockscrew function. Display packed in plastic storage case.

Greenlee part # 730EBB-120 Last time I inquired, they were around $450 in the states + Large 3/4" socket wrench, and 2" socket. I wouldn't use anything less than 19" long socket wrench. Estimated purchase price of $550 new.

This would be nice to own. CNC Shark Pro Plus Router, sold for $3,599.99 by ROCKLER

You can use the CNC Shark for carving, cutting, engraving, and etching hard materials that include, aluminum, MDF, wood, pvc, plexiglass, acrylic, and plastic.

You must supply a PC computer with USB 2.0 port and a Bosch Colt router (router sold separately). Simply connect the USB cable to the controller box and the other end to your computer (not compatible with Mac computers). The CNC Shark work table measures 28-1/2” wide by 36” long. The router itself can be moved over a 25” x 25” work path centered on the table. With its open end design work pieces longer than 36” can be placed into the machine, and continuous machining is possible with careful indexing of the workpiece. The table is much improved over the original Shark and Shark Pro in that its made of a blue anodized extruded aluminum channel which allows for great flexibility in clamping down workpieces. CNC Shark does include Vectrix CAM and 3D design software, but you'll want better graphics package like CorelDraw or Adobe Illustrator to create advanced artwork.

I don't know if this thread is still active, but I was checking out Gups Stargate Pyramid Case Mod and saw that he used a CD/DVD Drive to open and close a panel. I can't figure out how the panel actually pushes out first and then rises. Plus, where can you get mechanical mechanisms like this for models so that we can use them for case modding?
